sqoop上的Sybase IQ導入錯誤1

Question

我試圖導入數據，並且連接正常。列表表格語法給出了我的數據庫中的所有表格。但是當試圖運行導入查詢時，它給了我例外。

Sqoop命令：

sqoop import --connect 'jdbc:sybase:Tds:10.100.0.***:5500/DATABASE=iqprod1' --driver 'com.sybase.jdbc3.jdbc.SybDriver' --username "keswara" --password -p --query "select top 100 * from dw.DM_ADDRESS_ITC \$CONDITIONS" --target-dir "/user/keswara/WT_Address_Itc" --split-by 1 --verbose 

錯誤：

我已經在這裏錯過了什麼？非常感謝您的幫助！

Answer 1

您錯過了where。試試這個：

--query "select top 100 * from dw.DM_ADDRESS_ITC where \$CONDITIONS" 

查看sqoop documentation瞭解更多詳情。
